Field was arrested in July 2011 after two victims came forward to allege that he had sexually abused them at the Mid-Columbia Medical Center while they were semi-conscious and incapacitated. In all 12 victims eventually came forward. He pleaded guilty and was sentenced to 23 years in prison.

The most recent suits were filed Monday in Wasco County, by two women who worked as nurses at the hospital. Both say they were subjected to unwanted touching by Fields while undergoing treatment, one for headaches while the other underwent hand surgery.

The hospital has argued that Field was not an employee and it shouldn't be held liable for his actions. Both suits, however, claim the hospital had ample reason to take action before they suffered abuse, including two complaints from patients of sexual assault and three complaints from nurses of unwanted touching and sexually aggressive behavior.

The lawsuits ask for $8 million. The nurses' lawyer, Sean DuBois, said "We're suing them because they knew about what a creep this guy was and didn't fire him, didn't let the police know, didn't put him on probation."

There are a dozen cases filed against the hospital in all, four of which are scheduled for trial in October.
